So I’ve been testing my ppms before adding my Jacks 321 mix into my plants. They are in late veg about to flip to flower soon. Ive been doing 1000-1100 ppm, but noticed some type of deficiency (possibly potassium) so today I put in 1180-1200 ppms. When I went to test my runoff my meter shows a sign I’ve never seen before. I’m assuming the ppms are way too high to register. I’m growing in 5 gallon fabric pots and using fox farm bush doctor coco loco potting mix. I watered with 96 ounces of water and ended up with a cup of run off. I plan on using plain ph’d water next time to see if I can get an actual reading next time. Should I wait before flipping them now?
